Optitek ProLock Nikon F to Sony FZ lens mount adaptor
Used, but in very good condition and perfect working order. Nice and clean, with a smooth action.
These were at one time very sought after adaptors that allow you to mount Nikon lenses on Sony's F5 and F55 cameras. The red ring turns to manually control the iris: smooth and clickless! These were over £800 new, so grab a bargain here.
I will ship anywhere if buyer covers postage cost. Or, collection is fine from London SW16.
